UNITED STATES PATENT oFFIoE.

ORRELL ASHTON, OF LAWRENCE, MASSACHUSETTS, ASSIGNOR 'IO UNITED SH'OEMACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern Be it known that I, OBRELL AsH'roN, a

citizen of the United States, residing at the drawings indicating likeparts in the several figures.

This invention relates to machines for use in the manufactureof bootsand shoes and particularly to shoe beating m achines.

An object of the invention 1s to provide a machine of simpleconstruction comprising one or more tools adaptedto be rapidly vibratedor reciprocated for beating the bottom and preferably also the side of ashoe,

which mayv have been previously lasted, to shape the shoe on its sideand bottom faces adjacent to its edge, together with an meX- pensivemeans for actuating the tools.

A novel characteristic of this machine is found in the provision ofpower driven means for lifting or retracting the beating. means andthereby putting under tension or' increasing the tension of a yieldingelementthrough which the beating means is reversely actuated for doingits work.

A further characteristic of the .invention is found in novel means foravoiding the transmission of vibration from the beating tools and theiractuating mechanism to the treadle by which the movement of said toolsis controlled.

These and other features of the invention, including combinations ofparts and certain more important details of construction, willappear inconnection with the following description of a preferred embodiment ofthe machine and -will then be definitely pointed out in the claims atthe end of the description.

The figure is a side elevation of the machine in which portions arebroken away for disclosing details of construction.

The frame 2 of the machine has a pivot shaft 4 von which is mounted alever 5, the lower arm or tail of which is formed eccentrical to arotary driver 8, shown as provided with two oppositely disposed rollers10 ad apted as the driver turns to contact with the tail of the levernear the fulcrum shaft 1 Specification of Letters Patent.

'12 and an adjustable collar 18 on the upper end of the rod. The spring16 when com pressed by the treadle holds the tail of the lever 5 againstthe rotary driver. When the spring is not so compressed the lever isheld 1 with its tail away from the driver by a light spring 20 so thatthe lever remains at rest at all times except when the treadle is helddown while-the driver runs continuously.

The lever 5 pivotally supports at 24 an angle lever 25, the dependingarm of which is yieldingly held between spring-pressed plungers 26 inthe lever 5. The lower face of the front portion of the horizontal armof lever 25 is suitably shaped to pound the bottom of a shoe and thislever constitutes the bottom beating tool of the machine. The lever isprovided with bearings 28, 29 for a sliding rod 30 having on its frontend a tool 32 shaped and arranged to beat the side of the shoe forblocking or shaping the shoe in cooperation with the bottom beatingtool. The blocking tool and its supporting rod-3O slide lengthwise byreason of their inertia when the lever 25 is vibrated to beat the bottomof the shoe. In this sliding movement the blocking tool retreats as thepounding tool rises and then suddenly changes its direction as thedriver slides ofi" the tail of lever 5. The blocking tool then advancesas the pounding tool comes down and as the movement of the latter isabruptly checked by engagement with the work. A spring 34: is held undertension gagement of the roller 10 with the tail near the fulcrum of thelever. As a roller 10 passes the tail of the lever the spring 16, whichhas been put under compression by the action of the driver, is permittedto expand and actuates the beating tools downwardly to do their work.The force with which the beating tools will thus be actuated dependsupon the extent to which the treadle is depressed and the spring 16thereby compressed so that the operator can, by depressing the treadlemore or less, control the action of the beating tools upon the work. Theshoe is supported on the jack, which may be of known construction, andis arranged to permit the shoe to be turned for presenting differentportions thereof to the action of the beating tools.

The treadle is connected to the rod 14 by a link 40 and a U-shapedcasting 42. The treadle link is pivoted to the casting at 44 and to thesame pivot pin 44 is connected a swinging arm 45 connected tothe'machine frame by a pivot rod 46 against which the rear arm of theU-shaped casting also has hearing. The arrangement is such that the arm45 holds the casting 42 against the rod 46 when the treadle is released.When the treadle is fully depressed the parts are swung into the dottedline position wherein the arm 45 and the rod 40 occupy substantially therelation of toggle members which are straightened or on dead center andthe casting 42 rests upon the rod 46. This rod 46 thus steadies thetreadle and the parts connected with it and largely relieves them of thevibration which could otherwise be set up in them by the vibratorymovement of the lever 5 and the tools.

Having explained the nature of this invention and described a'preferredconstruc tion embodying the same, I claim as new and desire to secure byLetters Patent of the United States:
